NIGP 92558: Irrigation; Drainage; Flood Control/Engineering

NIGP 92558 Irrigation; Drainage; Flood Control/Engineering, an Item code, encompasses design, permitting, construction engineering, and physical implementation of stormwater conveyance, drainage infrastructure, flood mitigation, and water management systems serving counties, municipalities, and special-purpose districts. State and local governments are actively soliciting under this code for storm sewer pipe installation and replacement, drainage swales and catch basins, underdrain systems, erosion and sediment control, flood control channel design, and related engineering services tied to capital projects in infrastructure-constrained or flood-prone areas. Issuing bodies include county boards (Greenville County South Carolina, Pasco County and Orange County Florida, Harris County Texas, Galveston County Texas), cities (Orlando, Brownsville, Alpharetta, Dalton, San Marcos, Cincinnati, Valdosta), municipal water and wastewater districts (West Basin Municipal Water District California, Metropolitan Sewer District of Greater Cincinnati Ohio), special districts (Nantucket Islands Land Bank Massachusetts), and state environmental protection and transportation departments (Florida DEP, Georgia DOT). The code sees consistent activity across design-phase qualification requests (RFQ, RFP) and construction-phase invitation-to-bid (IFB, ITB) notices, with response deadlines ranging from mid-June through August 2026.

Recent opportunities reflect a geographic concentration in Florida and the Southeast, with secondary activity in Texas, Georgia, California, and scattered Northeast corridor locations. Greenville County South Carolina is soliciting sealed bids for the Merrifield Park Drainage Improvement Project (IFB #27000, due July 24, 2026), encompassing approximately 2,380 linear feet of storm drainage pipe ranging 18 to 36 inches in diameter, 24 catch basins, asphalt restoration, and site stabilization within 150 consecutive calendar days; Orange County Florida is requesting bids for underdrain installation and repair services (Y26-1003, due August 4, 2026) at an estimated five-year value of $19.6 million on a unit-price basis; and West Basin Municipal Water District is awarding up to five on-call engineering agreements (RFPTH0128, due July 14, 2026) totaling approximately $3 million for hydraulic modeling, feasibility studies, design services at 30% and 100% levels, and construction support across water and wastewater facilities in the Los Angeles coastal area. Additional representative solicitations include Flagler County Florida for First Avenue Drainage Improvements Phase 2 (ITB 26-ITB-017, due July 29, 2026) with storm sewer and swale work, and the Georgia Department of Transportation for on-call Special Drainage Studies in three districts (RFQ-484-061526, due June 15, 2026) emphasizing hydraulic modeling, scour analysis, and NEPA compliance. Prevailing wage, bonding (5 to 10 percent bid bond, 100 percent performance and payment bonds), professional liability insurance, and FDOT prequalification or equivalent state-level contractor certification are standard requirements; many solicitations include set-asides or preferences for small business enterprises, local vendors, and disadvantaged business classifications where applicable by state or federal funding source.
